Delivery Modes

A delivery mode defines how the endpoints deliver messages in the JMS transport.

TIBCO ActiveMatrix Adapter for SAP supports the following delivery modes:

Publication Service and Request-Response Invocation Service
- Persistent
  The message is available to a JMS client even if the JMS server goes down.
- Non-persistent
  The message is not available to a JMS client if the JMS server goes down.
Subscription Service and Request-Response Service
- Durable
  The service is registered with the JMS server. The JMS server holds messages sent to a durable Subscription Service or Request-Response Service service until they are consumed by the service. If the service is down and restored, it receives the messages that arrived at the JMS server while the service was down.
- Non-durable
  The service is not registered with the JMS server. The JMS server does not hold messages sent to a non-durable Subscription Service or Request-Response Service service. If the service is down and restored, it cannot receive the messages that arrived at the JMS server while the service was down.
Note: These various delivery modes are available only when the connection factory Type is Topic
